Can I use 19V instead of 12V?

Any device that was designed to run at 12V is likely to be fried by 19V. It might catch fire, even though it’s not very likely. You must have an equal or higher current rating in order to use an AC adapter.

Will a 19V TV work on 12V?

19v is way to high to connect to a 12v device. First, the voltage MUST MATCH the requirement. Then the device supplying the power has to be able to supply that current. If your device needs 3 Amps, can the charger supply that.

Can you use a 19V adapter on a 15V device?

If you have a 15V LCO (LiCoO2) battery, then its voltage upper limit is 17V. So, 19V would be too high to charge this 15V pack. Either use the device manufacturer’s charger or use a DC-DC step-down converter to reduce the 19V down to 15V or 17V (if it’s LCO).

Can you charge a 12V battery with a 19V charger?

NO you cannot charge your 12V AGM battery directly with a 19V Laptop power supply. You need a battery charger. The laptop power supply IS NOT a battery charger, it is a fixed voltage SMPS power supply.

Can I use a 24V power supply on a 12V?

The 24V supply can be used but you need to add a series resister to drop the voltage by 12v.

Can you run a TV on a 12V battery?

Many people wonder how to power a TV with a car battery. It’s actually easier than you may think. Powering your home TV from the 12-volt lighter socket in your car, truck or RV is possible. This adapter will clamp onto the battery terminals and provide an outlet which the power inverter can plug into.

Can a TV run on 12V?

Twelve-volt TVs work just like regular TVs except for how they get power. A standard TV plugs into a 110/120V or 230V plug. Whereas this television draws 12V, and you can wire it straight into a 12V or sometimes 24V battery. You don’t need an inverter to run it, as it can run directly off your RV house battery.

Can a 12-volt car battery power a TV?

A 12-volt car battery can be used with a power inverter to power a TV. However, since a car battery is a starter battery, it will be damaged by deep discharges for powering electronics. In many instances when were are looking at the “ability” for a car battery to power a TV for even a short time, the answer is YES. Yes, it can power the TV.

How long will a 12-volt battery power a 30-watt TV?

You’ve got access to a 12-volt battery in your car… hmmm… A car battery can power a 30-watt TV for about 10 hours until the battery is 50\% discharged. However, the answer has many variables.

How many amps does a 12 volt TV use?

For example, the 15.6″ one from Amazon draws 2 amps at 12 volts which is 24 watts. That would get you 12.5 hours of usage from the car battery example above! The 22” TV draws a total of 36 watts, which would get you 8.3 hours of use from a car battery!

Can a 12V power supply be used in a 19V car?

There are examples for different outcomes. If that “12V” device was designed to be used in cars/boats, from the nominally 12V supply that’s around 14V when the engine is running, and might carry transients up to 200V, then it must be able to tolerate 19V. At least for a short time.
